Divine justice and finality

فَمَا زَالَت تِّلْكَ دَعْوَىٰهُمْ حَتَّىٰ جَعَلْنَـٰهُمْ حَصِيدًا خَـٰمِدِينَ

And that declaration of theirs did not cease until We made them [as] a harvest [mowed down], extinguished [like a fire].

قُلْ يَوْمَ ٱلْفَتْحِ لَا يَنفَعُ ٱلَّذِينَ كَفَرُوٓا۟ إِيمَـٰنُهُمْ وَلَا هُمْ يُنظَرُونَ

Say, [O Muḥammad], "On the Day of Conquest the belief of those who had disbelieved will not benefit them, nor will they be reprieved."
